Mario is one of gaming's most recognizable characters, and his voice has long been sampled and remixed by fans for short meme clips. The bruh format itself comes from internet slang for disbelief, and pairing that reaction with Mario's cheerful character creates a funny contrast that travels well across social media and gaming streams. Because the clip is short and instantly understood, creators keep reusing it as a quick reaction sound rather than a longer joke, which has helped it stay popular in edits and compilations.
